TECHNICAL FIELD

The disclosure relates to the field of data processing technologies, specifically to the field of text storage technologies, and more particularly, to a method for storing a determinant text, an electronic device, and a computer-readable storage medium.

BACKGROUND

A graph database, originating from Euler and graph theory, is a graph-oriented/graph-based database. The graph database is a database to store and query data in a data structure of “graph”, rather than a database to store pictures, for example. The main input data of the graph database is determinant texts, and data retrieval is realized through large-scale storage of determinant texts.

In the related art, the following two methods are generally used to store determinant texts. The first one, the determinant text is converted into data in a json (JavaScript Object Notation) form for storage. However, in actual storage processes, data expands tremendously and a retrieval duration is long. The second one, the determinant text is stored sequentially, but the determinant texts stored sequentially have insufficient compression ratios, resulting in too many redundant fields and low retrieval efficiency.

DETAILED DESCRIPTION

The following describes the exemplary embodiments of the disclosure with reference to the accompanying drawings, which includes various details of the embodiments of the disclosure to facilitate understanding and shall be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the disclosure. For clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

In order to solve problems of insufficient compression ratio and low retrieval efficiency in a method for storing a determinant text in the related art, the disclosure provides a method for storing a determinant text. With the method for storing the determinant text in the disclosure, the determinant text that is to be stored is obtained, and the determinant text includes the plurality of fields. The valid fields are obtained from the plurality of fields. The field type table is queried according to the valid fields to generate the data description field of the determinant text. The value storage field of the determinant text is determined according to the contents of the plurality of fields and the field type table. The data description field and the value storage field are stored to store the determinant text.

A method for storing a determinant text, an apparatus for storing a determinant text, and an electronic device according to embodiments of the disclosure are described below with reference to the accompanying drawings.

FIG. 1 is a flowchart of a method for storing a determinant text according to some embodiments of the disclosure.

As illustrated in FIG. 1, the method for storing the determinant text includes the following.

At block 101, a determinant text that is to be stored is obtained. The determinant text may include a plurality of fields.

In some embodiments of the disclosure, the determinant text, also called a CSV (Comma-Separated Values) text, is table data stored in a form of a text file. For example, the following table is an example determinant text.

name age city Zhang San 20 Beijing Li Si 26 Shanghai Wang Wu 30 Guangzhou

In some embodiments of the disclosure, before storing the determinant text that is to be stored to the database, the determinant text that is to be stored is obtained first, and the determinant text that is to be stored includes the plurality of fields.

As can be seen from the above table, when storing the determinant text, the determinant text that is to be stored includes the plurality of fields, and “columns” in the table may be referred to as the fields, and each field contains information on a particular topic. As mentioned above, the determinant text includes a “name” field, an “age” field, and a “place of residence” field (e.g., a “city” field). For another example, in the “address” database, “name” and “contact number” are attributes common to all rows in the table, so these columns are called the “name” field and the “contact number” field.

At block 102, valid fields are obtained from the plurality of fields, and a field type table is queried according to the valid fields to generate a data description field of the determinant text.

At block 103, a value storage field of the determinant text is determined according to contents of the plurality of fields and the field type table.

In some embodiments of the disclosure, the field type table includes a plurality of types. Each of the plurality of types includes a corresponding type identifier and a set of subtypes. Each subtype in the set of subtypes has a corresponding subtype serial number and an attribute. The attribute includes an attribute number, an attribute type, a default value and a determination on whether a corresponding value is allowed to be null.

In some embodiments of the disclosure, the valid fields in the plurality of fields included in the determinant text may refer to fields that need to be stored in the determinant text that is to be stored.

In some embodiments of the disclosure, the determinant text that is to be stored may be divided into two fields, namely the data description field and the value storage field.

In some embodiments of the disclosure, after obtaining the determinant text that is to be stored, the valid fields in the plurality of fields included in the determinant text may be obtained, and the field type table may be queried according to the valid fields to generate the data description field of the determinant text.

In some embodiments of the disclosure, the value storage field of the determinant text may be determined according to contents of the plurality of fields included in the determinant text that is to be stored and the field type table.

At block 104, the data description field and the value storage field are stored to store the determinant text.

In some embodiments of the disclosure, after generating the data description field and the value storage field of the determinant text data that is to be stored, the data description field and the value storage field constitute data of the determinant text for storage. Therefore, the compression and storage of the determinant text is realized, and the compression rate during data storage is improved.

Most of data in the determinant text may have default values, for example, “nation” may have a default of “Han”, “Gender” may have a default of “Male” or “Female”. For the value repeatedly used, the default value may also be set, then there is no need to store this value when storing, the value may be expressed by one bit, and the compression rate when performing storage on the determinant text is very high.

For example, as illustrated in FIG. 2, for data, a gray portion is the data description field. The valid fields are marked in FIG. 2. The determinant text is that name: “Xiaodu Online”, Company nature: “science and technology innovation”, and there is no “legal person”, “establishment time” and “registered capital” in the determinant text. When storing the determinant text, there is no need to store “legal person”, “establishment time” and “registered capital”, and it only needs to mark the fields in the attribute states. “Company nature” is directly written as 0 firstly, and after querying the determinant text, this field is an enumeration value, and 0 represents the first enumeration value, so the value of “Company nature” is “science and technology innovation”.

If the “establishment time” field is obtained, and it finds that the field does not exist through the attribute state, the determinant text is directly queried, and if there is a default value, the default value is returned.

Compared to the problem of inefficient retrieval in the sequential storage of the determinant texts, after storing the determinant text in the disclosure, when retrieving the content of the determinant text, since the attribute number or even the entire data description field may be stored, the status of the field is quickly located during retrieval, for example, whether the field exists, and where is the field located in the value storage field.

In some embodiments of the disclosure, the determinant text that is to be stored is obtained, and the determinant text that is to be stored includes the plurality of fields. The valid fields are obtained from the plurality of fields, and the field type table is queried according to the valid fields to generate the data description field of the determinant text. The value storage field of the determinant text is determined according to the contents of the plurality of fields and the field type table, and the determinant text data and the value storage field are stored as data of the determinant text. In this solution, the data description field and the value storage field of the determinant text are determined, and the data description field and the value storage field constitute the data of the determinant text for storage, thus the compression ratio of the determinant text for storage and data retrieval effectiveness are improved.

As a possible implementation, in the above block 102, when querying the field type table according to the valid fields to generate the data description field of the determinant text, a type corresponding to each of the valid fields may also be obtained from the field type table, and type ID data is generated according to a type identifier corresponding to the type corresponding to each of the valid fields. Subtype serial numbers of subtypes in a set of subtypes, of the type corresponding to each of the valid fields, may be obtained, and attribute value data is generated according to the corresponding subtype serial numbers. Further, according to the type ID data and the attribute value data, the data description field is generated. The implementation process is described in detail below in combination with FIG. 3. FIG. 3 is a flowchart of a method for storing a determinant text according to some embodiments of the disclosure.

As illustrated in FIG. 3, the method for storing the determinant text may include the following.

At block 201, a type corresponding to each of the valid fields is obtained from the field type table, and type ID data is generated according to a type identifier corresponding to the type corresponding to each of the valid fields. That is, each type corresponding to the determinant text in the field type table is obtained, and the type ID data is generated according to each corresponding type identifier.

In some embodiments of the disclosure, the types in the field type table may be an integer type, a floating type, a character string type, an enumerated type, and a date and time type.

The enumerated type is a very special type, basically not in other databases. Similar to a foreign key table of mysq1, in fact, in a real example, the field types of a large part of data are enumerated types, for example, “Company Type”, “Industry”, “Gender”,

“Transaction Type”, and “Country & Region”.

In some embodiments of the disclosure, after obtaining the plurality of fields included in the determinant text, the type to which each field belongs is determined in the corresponding field type table, and type ID data is generated according to the type identifier corresponding to each field.

For example, if the determinant text includes a company field, a bank field, and a personal field, each field corresponds to one type ID data, for example, the type ID data corresponding to the company field may be num1.

At block 202, subtype serial numbers of subtypes in a set of subtypes of the type corresponding to each of the valid fields are obtained. That is, the subtype serial numbers of the subtypes in the sets of subtypes, of the types corresponding to the valid fields, are obtained.

In some embodiments of the disclosure, not all fields in the plurality of fields included in the determinant text are valid fields. In order to improve the compression rate when storing the determinant text, the subtype serial numbers of the subtypes in the sets of subtypes, of the types corresponding to the valid fields, may be obtained.

At block 203, attribute value data is generated according to the corresponding subtype serial numbers.

In some embodiments of the disclosure, after obtaining the subtype serial number of each subtype, attribute value data is generated according to a determination on whether each subtype exists in the determinant text.

For example, the field types included in the field type table and in the determinant text are “name”, “legal person”, “company nature”, “establishment time” and “registered capital”, and the set of subtypes corresponding to the field type “company nature” are “science and technology innovation”, “agriculture and forestry”, “education” and “others”. After obtaining the subtype serial number of each subtype in the set of subtypes, corresponding to each of the types of the valid fields, it is determined that the attribute value data of the type “name” and “company nature” both is 1, and the attribute value data generated by the remaining types are all 0. There is no need to store fields whose attribute value data is 0, thereby improving the data compression rate during data storage and saving storage space.

At block 204, the data description field is generated based on the type ID data and the attribute value data.

Both the type ID data and the attribute value data are variable-length integers. The type ID data and the attribute value data are compressed and stored by using “a reference length plus a step length” to avoid reserving a lot of space during data storage. Therefore, the compression rate of data storage is improved, and the space for data storage is saved.

The variable-length integer employs 1 flag bit and 7 data bits to compress a positive integer value. The role of the flag bit is to indicate whether the value of the remaining data bits except for 7 data bits, is 0. The specific calculation method is as follows. An AND operation is performed between the value and 0×7f. If the value is 0, the effective data bit of the value is 7 bits, otherwise, the value is 1, which indicates that there is still valid data, and the value is shifted to the right by 7 bits to continue the above steps until the value is 0, thereby achieving compression and storage of data and improving data compression rate.

In some embodiments of the disclosure, after determining the type ID data corresponding to each field in the determinant text and attribute values corresponding to the valid fields, the data description field is generated according to the type ID data and the attribute value data.

The method for storing the determinant text according to the embodiments of the disclosure, by obtaining the type corresponding to the determinant text in the field type table, and the type ID data is generated according to the type identifier of the corresponding type. The subtype serial number of the subtype in the set of subtypes, of each type corresponding to the valid fields, is obtained. The attribute value data according to the corresponding subtype serial number is generated. Data description field is generated based on the type ID data and the attribute value data. As a result, the data compression rate during data storage is improved, and storage space is saved.

As a possible implementation, at the above block 103, when determining the value storage field of the determinant text according to the contents of the plurality of fields and the field type table, subtype serial numbers corresponding to the valid fields are obtained, and storage locations of the subtype serial number in the value storage field are obtained to store the valid fields based on whether the valid fields are character strings. The above process is described in detail below in combination with FIG. 4. FIG. 4 is a flowchart of a method for storing a determinant text according to some embodiments of the disclosure.

As illustrated in FIG. 4, the method for storing the determinant text includes the following.

At block 301, subtype serial numbers corresponding to the valid fields are obtained, and storage locations of the subtype serial numbers in the value storage field are obtained.

In some embodiments of the disclosure, the determinant text that is to be stored is obtained, and the valid fields in the plurality of fields included in the determinant text are determined. Further, the subtype serial numbers corresponding to the valid fields and the storage locations of the subtype serial numbers in the value storage field are obtained.

For example, if the determinant text that is to be stored includes types of “company”, “bank”, and “personal”, the type of “company” includes subtypes of “name”, “legal person”, “company nature”, “establishment time” and “registered capital”. In addition, each subtype has a corresponding subtype serial number and attribute. The attribute includes an attribute number, an attribute type, a default value, and a determination on whether the value is allowed to be null.

Taking the example in FIG. 2 as an example, suppose the determinant text that is to be stored is the name: “Xiaodu Online”; company nature: “science and technology innovation”, the subtypes corresponding to the valid fields of the determinant text that is to be stored may be “name” and “company nature”. Further, the subtype serial numbers corresponding to the valid fields and the storage locations of the subtype serial numbers in the value storage field are obtained.

At block 302, it is determined whether any valid field is a character string.

In some embodiments of the disclosure, after obtaining the valid fields of the determinant text that is to be stored, it is determined whether any valid field is the character string, so as to store the valid field according to the type corresponding to the valid field.

At block 303, if it is determined that any valid field is a character string, content of the corresponding character string is stored to the storage locations of the corresponding subtype serial numbers in the value storage field.

In some embodiments of the disclosure, when it is determined that any valid field of the determinant text that is to be stored is the character string, the character string content of the valid field may be stored to the storage locations of the corresponding subtype serial numbers in the value storage field.

At block 304, if it is determined that any valid field is not a character string, attribute values of the corresponding subtypes are obtained, and the attribute values are stored to the storage locations of the corresponding subtype serial numbers in the value storage field.

In some embodiments of the disclosure, when it is determined that any valid field of the determinant text that is to be stored is not the character string, the attribute values of the subtypes corresponding to the valid field are obtained, and the attribute values are stored to the storage locations of the corresponding subtype serial numbers in the value storage field.

For example, as illustrated in FIG. 2, since the attribute value of the subtype corresponding to “company nature” is 0, after querying the field type table, it is determined that the field corresponding to “business nature” is an enumeration type. 0 represents a first value of the enumeration type, so the value corresponding to “company nature” is “science and technology innovation”. Therefore, after obtaining the attribute value of the subtype corresponding to “company nature”, the attribute value is stored to the storage location of the subtype serial number in the value storage field.

With the method for storing the determinant text, by obtaining the subtype serial numbers corresponding to the valid fields, and the storage locations of the subtype serial numbers in the value storage field, if it is determined that any valid field is the character string, the content of the character string of the valid field may be stored to the storage locations of the subtype serial numbers in the value storage field, and if it is determined that any valid field is not the character string, the attribute values of the subtypes corresponding to the valid field are obtained, and the attribute values are stored to the storage locations of the subtype serial numbers in the value storage field. Therefore, the compression ratio when storing the determinant text that is to be stored is improved, and the storage space is saved.

In order to implement the above embodiments, the embodiments of the disclosure provide an apparatus for storing a determinant text.

FIG. 5 is a block diagram of an apparatus for storing a determinant text according to some embodiments of the disclosure.

In this solution, the data description field and the value storage field of the determinant text are determined, and the data description field and the value storage field constitute the data of the determinant text for storage, thus the compression ratio of the determinant text for storage and data retrieval effectiveness are improved.
